The detection device is technically characterized in that (1) by adopting a double-nozzle structure, the device is capable of resolving the problem of respectively detecting air-jet loom reeds of 12 degrees or 6 degrees without changing position of a pilot tube, (2) a horizontal line of the device moves up and down, and the device adopts a dovetail device, and is lifted by a spiral screw, quantified by a dial gauge and adjustable from left to right, (3) the pilot tube is protected via a protection wing, and (4) an included angle of 20 degrees is formed between the pilot tube and a front plane of a detected air-jet loom reed. The detection device has the advantages that detection result obtained by using the detection device is approximately close to a practical value of the air-jet loom reed, detection process is speedier, and operation is more facilitated, thereby providing technical guarantee for integrating detection methods of textile enterprises and air-jet loom reed manufacturers in cotton textile industry to meet industrial requirements.
Description
(1), technical field
The utility model relates to a kind of detection equipment of field of textiles, particularly relates to a kind of used in jet loom reed atmospheric pressure value detector air drain pressure test device.
(2), background technology
Air-jet loom is a kind of of shuttleless loom, and it is having certain advantage aspect high speed, high yield, high-quality, the low energy consumption, and adapted breed is extensive.The gas reed works the effect of beating up in weaving process, its air drain is the weft yarn flight corridor, and can weft yarn smoothly by closely related with geometric configuration flatness, the smoothness of air drain.The air flow losses of gas reed directly influences the energy consumption of air-jet loom, influencing air flow losses mainly is the geometric configuration flatness and the smoothness of gas reed air drain, but how to detect the airslide of gas reed whether qualified (the used in jet loom reed has industry standard) is a very crucial problem.Family surplus used in jet loom reed (hereinafter to be referred as " gas reed ") production firm has at home reached ten at present, mostly used gas reed detector is for 80～nineties from Japanese or the Europe introduction, its form is different.I belong to the domestic initiation product by the gas reed detector of center independent development development, and the advantage that combines Europe, day product adopts the working method of simulation air-jet loom, vertical scheme of putting.The two-pack form of nozzle can be suitable for Europe, the product of day simultaneously.The testing result that facts have proved this scheme is near the actual value of gas reed.
(3), summary of the invention
The purpose of this utility model is to provide a kind of reed of gas accurately and fast pick-up unit, that is: used in jet loom reed atmospheric pressure value detector air drain pressure test device for the cotton spinning industry gentle reed manufacturing enterprise of enterprise of weaving cotton cloth.
The technical solution of the utility model is to realize like this.
A kind of used in jet loom reed atmospheric pressure value detector air drain pressure test device is used in used in jet loom reed atmospheric pressure value detector, and the technical characterictic of this pick-up unit is as follows:
This device adopts vertical folder reed, the jet form of twin-jet nozzle simulation loom.The position form of auxiliary jet on the loom and air-flow are injected the angle to be transplanted on the detector.
1, the twin-jet nozzle structure and with the positional structure of pitot tube, the employing of twin-jet nozzle structure, this structure is different from other detector and uses one-jet advantage to be: can solve under the state that does not change the pitot tube position, detect the used in jet loom reed (seeing accompanying drawing 1) at 12 ° or 6 ° angles respectively.
2, the horizontal line of this device moves up and down, and adopts dovetail device (seeing accompanying drawing 2), and helical screw promotes, and dial gauge is quantitative.The left and right sides is adjustable.The advantage of this unit: simple to operate when being elevating movement, variation＜0.01mm.
3, pitot tube band flap protection, this improvement have solved the shortcoming (seeing accompanying drawing 3) that pitot tube is easily bumped distortion basically.
4, pitot tube and tested gas reed frontal plane are 20 ° of angles, and this design has guaranteed that the air-flow of nozzle injects the angle of injecting that the angle meets the air-jet loom auxiliary jet.Compare with direct-injection type, this mode has been quoted loom auxiliary jet form, more near virtual condition (seeing accompanying drawing 4).
The technological process and the technical parameter of this device are as follows:
Adopt the jet form of two-pack nozzle simulation loom, vertical folder reed.Be the initiative of my unit, on an instrument, can be suitable for Europe (6 °) and Japan's (12 °) two kinds of multi-form gas reeds simultaneously.Adopt the auxiliary jet of 80mm distance when promptly detecting 12 ° of gas reeds, adopt the auxiliary jet of 110mm distance when detecting 6 ° of gas reeds.
The principle of work of this device is as follows:
Auxiliary jet is ejected into the 0.5MPa compressed air stream on the bottom surface of gas reed airslide with fixed angle, and this moment, pitot tube received reflected gas stream.And the situation of gas reed received in the lump, pass the signal to computing machine by sensor-A/D interface circuit and relatively be made into coordinate diagram intuitively by analysis.Store this information simultaneously and indicate regulator that the problem areas of gas reed is carried out reconditioning then, to reach the standard-required of qualified gas reed.
Usefulness of the present utility model is: adopt the resulting testing result of this detection pick-up unit very near the actual value of gas reed, testing process is more quick, operation is convenient more, be the weave cotton cloth detection method of gentle reed manufacturing enterprise of enterprise of unified cotton spinning industry, the needs that adapt to industry provide technique guarantee.
